Traditionally, wind analysis procedures based on the ‘‘gust loading factor’’ approach and experimental techniques involving the high frequency base balance and the ‘‘stick-type’’ aeroelastic model test have assumed ideal structural mode shapes, i.e., linear lateral modes and uniform torsional modes. The influence of nonideal mode shapes manifests itself through modifications in the generalized ...

We report Fano resonances in a multimode square glass micropillar resonator; the resonances were obtained by using angle-resolved prism coupling. Our experiments reveal characteristically asymmetric line shapes of high-Q resonances and of detuned low-Q resonances in multimode reflection spectra. The asymmetric resonance line shapes evolve for an approximately pi phase within a 0.5 degree range ...

Coriolis accelerations in a rotating body of fluid produce restoring forces for disturbances that depart from solid-body rotation, resulting in wave-like motion known as inertial waves. This kind of behaviour can be important in geophysical and technological applications (e.g. planetary core dynamics, instabilities in spinning rocket fuel tanks). For simple container shapes and for solid-body r...

Studies of raindrop shapes, oscillation modes, and implications for radio wave propagation are presented. Drop shape measurements in natural rain using 2-D video disdrometers (2DVDs) are discussed. As a representative exception to vast majority of the cases where the “most probable” shapes conform to the axisymmetric (2,0) oscillationmode, an event with a highly organized line convection embedd...

This paper presents a progressive numerical model validation of bowstring-arch railway bridge based on the analysis experimental data from different structural response measurements, namely, static deformations under environmental actions, modal vibrations, and transient dynamic responses traffic loads. work also addresses an integrated approach that uses health monitoring (SHM) measurements in...

This paper presents the design and implementation of H-bridge converter with additional switch legs (HA converter) which acts as AC-DC rectifier as well as DC-AC inverter. In this topology a solid connection is provided between the grounds of the input and output terminals, which reduces common mode noise and makes the converter suitable for PV PCS in dc distribution system or stand-alone power...

A cohesive element formulation is proposed that provides a general framework to approximate experimentally measured Traction–Separation Law (TSL) shapes. Unlike other approaches, it does not assume specific TSL shapes, such as bi-linear or exponential. The shapes are defined generally, in piecewise-linear fashion, and Mode I shear (Mode II III) TSLs can have different Furthermore, added general...
